Gen III

"Development Pending – The Gen III is designed to work with the LTCC coil pack system offered for the LT1. This is a rotorless system with a billet aluminum cap. We plan to offer this as an upgrade from your current dynaspark as well as purchased new. Check back often for updates"

I'm wondering if this is an "optical wheel only" version of an optispark? The description is sort've confusing as it says it's rotorless but they also say it has a cap. (Maybe the cap is just an aluminum cover that goes directly over the optical wheel?) Hopefully they'll keep the price lower than the MSD model because the MSD is just overkill for guys running the LTCC system.
